METHODS This is a randomized clinical trial in which 433 active employees with low back disorders were randomly assigned to one of two study groups: 1) back support plus education on back health; or 2) education on back health only. Demographic, health, medical, and job factors were recorded. Outcomes were evaluated over a twelve month period and included self-reported measures of back pain, back pain disability level, physical health, mental health, back pain recurrence and administrative measures.
